The trimming rollers 13 and 11i are caused to revolve by the .following mechanism: Sccured to the under ace of the table 1 are brackets 22 which form bearings for and support the horizontal shaft 23 of an urinature of an electric motor 24. The armature shaft 25S aisobears a pulley 25 (see Fig. Ll)

. adapted to drive a belt 26. Mounted in suit- /sprocket'chain Bl the upper end of which passes around a sprocket wheel on a shaft 36. mounted in a housing 37 on the upper face of the table 1, (see Fig. t). The shafts 28 and 36 are of sufficient length to permit the sprocket wheels 33 :ind to he placed at one side oi the table so that the sprocket chain from one'to the other is permitted, Also mounted on the shaft is a sprocket Wheel 38 over WlliehV runs a sprocket chain 39 which also runs over a sprocket Wheel el() mounted on the shaft 41 supported at one end by a housing 42 and otherwise supported in a pair of housings 43. The shaft lll bears a sprocket wheel @A and extending between the sprocket `Wheel 20 on the shaft 16 and the sprocket Wheel e4: on the shaft Ail is a sprocket chain 495 so that as motion.

is communicated by the motor 24 through the shaft to the pulley 29 motion is also communicated `through the sprocket chain Belto the mechanism just described.

Mounted at the left, in. Fig. 1, of the trimming rolls 13 and 1% is a stationary guiding plate -lG provided with an aperture through which the new trimmed bead-core passes, and to the left of the guiding plate fld are a pair olf housings 4.7 (sec lfigj), provided with bearings for a pair of shafts on which are mounted Aroughing rolls #LS and 49. The upper roll 4S being mounted ou a shaft 50 and the lower roll elf) being mounted on a shaft 5l. The faces of the rolls 4:8 and 4:9 are fashioned to generally approximate the shape of the bead-core and are provided with roughing members or knives 52. These two rolls are adapted to be rotated in aI reverse direction to the trimmingrolls l'and 1st and in a direction reverse to the travel of the bead-core 9. rlhe function of these two rolls is to slightly roughen the surface of the bead core so that the subsequently applied ccnent will adhere thereto more pcfrnrw nen'tly` and become slightly incorporated with the superficial portions thereof. vThese rolls i8 and 49 are rotated as follows: Mounted on the shalt 31 are a pair of pulleys and 5l. Mounted on the shafts and 5l are a pair of .pulleys .35 and 56 respectively'. Adapted to run on the pulleys 53 and 55 is a belt 56 and connecting the pulleys 54 and 56 is a belt 5T which latter is@ crossed between the two pulleys so as to cause the roll 48 and 49 to rotate in opposite directions and their peripheral portions lia-ving the roughing tools 52'to move in an opposite direction to le movement' of the bead core 9. It Will be obvious, of course, that the revolutions of the pulleys 53 and 54 is obtained throughl the medium of the belt 26, already described. l

Mounted at the left of and adjacent to they mechanism described in the preceding para, graph are a pair of drawing rolls (see Fig.

G) .designated bythe reference numerals 58p,-

and 59 between which the trimmed and' roughened bead passes and b 'whichfits movement is secured." These eedl rolls 58 and 59 are mounted ony suitable shafts 60. andLl-l in the housings 43, this housing likeV all the housings 'being provided with suitable boxes for the shafts'inounted therein.

The feed roll 59 is provided with periphy 'sponds to the two faces of the bead core which is not engaged by points 63. The rotation of the shaft l1 is secured, as yhas already been described, through the mediumy of the sprocket chain or linked belt 39. The small projections 63 are of so minute a character that they do not injurethe bead core which they engage and their engagement withv the bead core is' increased through the medium of ,the pressing roll 58 which forces the. core against these points, thereby etico tually securing traction of the points 63 with respect to the bead oor-e.

Mounted on the upper face of the table 1, to the left in Fig. l, of the housings 4.3 is a coating tank 64 adapted to contain a liquid cement through which vthe bead core is arranged to pass and receive a coating of a siccative rubber cement. The tank embodies a body member adapted to contain llG liquid cement forming a bathland is provided at the right end in Fig. 1 with a pair of arms 65 the outer ends of which are provided with bearings for the shaft of a guiding roller 66 over which the bead Core 9 passes. The opposite end of the tank is also provided with a pair or' arms o? proif'ided with bearings for supporting the axle or a flu guiding roller 68. 1n order to hold the strip 9 of bead core submerged in a bath during its progressive movement the following mechanism is employed: (see Fig. 12).

Secured to one side of the tank 64 is a lug 09 provided with a vertical aperture constituting av bearing forminr a support for a 'lshaped member 70 in which entends a horizontal shaft with one end positioned over the open portion of the tank and on which is iixedly mounted an arm 71 bearing a roller T he opposite end of the shaft is provided with a iXedly secured arm 713 the lower end of which is provided with an enlargement .el Ain which is a horiaontally-shiftable pin 'T5 adapted to be forced into a. suitable aperture in the side wall of the tank for holding the two arms i a determinate position and constituting locking pin for this purpose. The roller.

I2 is adapted to hold the strip 9 within the bath during its progressive movement through the medium and if it is desired at any time' to permit the passage of the strip 9 without a. subniersion in the bath the locking pin T5 is withdawn and the arm 73 oscillated thereby raising the roller 72' out of the bath. immediately adjacent to, and

atthe left of the bath 64C is an upright bracket TG which bears at itsupper end a guiding; roll 7T. The function of the guiding` roll 77 is to change the line of movement of the by which the siccative coating placed on the strip in the'hath Se is partially'dried and thereby thickened. The drying mechanism consists of an elongated steam jaclreted cylinder T8 into the interior of the jacket of wl'iich steam is admitted by inlet pipe T9 and exhausted through a pipe S0. rEhe strip 9 is adapted to pass through the open central portion of the drier and the drying operation is increased by the forcing of compressed air into the cavity in the cylinder through which the strip 9 passes by means of anfinlct pipe Si To left.l in 1 52. of t 'TS an upright uaclret S2 which is to revolub y support a 1guiding roller 9S for guiding the 4trip 9.

he drying device Y The cenrie guiding rollers 77 and 83 are approximately in a horizontal plane so that the srip 9 easily guided through the drying device just described during its progressive movement,

Secured to Athe under face of the table 1 etween the pairs of legs Q and 3 area pair of brackets Si supporting a shaft for a 'rcel on which wound a narrow strip of rubberized fabric. 9.9 in an uncurcd condition and it is'customary to interpose between the windings of the fabric S6 'a layer of fabric, xaeneraliy muslin, to preyeut the successive windin1s from sticking together and the separatingA layer 87 of cloth is wound onto a strip 9 toward a drying tank take-'up roller 88 supported by pivot arms 89 during the unwindinggv of the fabric 86.

The take up roll is adapted to run on the outer face of the coil of rubberized fabric 86 and receives motion therefrom during .the ltaking-up process.y The rubberized fabric 8G is carried upwardly through a suitable opening 90 in the table and over a convex; lguiding roller 91 and from there is carried forward and applied to the bead coreby the following mechanism.

Positioned at the left of the convex roller 91 in Fig. 2 is a; pairof housings 93 (see Fig. T) in which are bearings for the shafts of an upper roller 94 and lower roller, 95. The function of the two rollers 94- and 9o is to press the wider and under face of the pre-- viously cement coated bead-core against the strip 86 and thereby cause the adhesion of:

the strip of fabric to this face of the core. lhe lower roller 95 is provided with lateral flanges 96 for guiding and holding the strip of fabric during its passage between the rolls. These flanges are spaced a sufficient distance apart to easily receive and guide the strip of fabric. The central portion of the roller 95 is provided with shallow cir cumferential grooves' into which the fabric and a portion of the bead are forced by the upper roller 94. theA periphery ofthe latter beingy fashioned to engage the other two sides of the triangularlyshaped core. Asv

the strip of fabric 8G leaves" the rolls 9i and 95 the bead core is adherent to its central upper face and with the unused or unoccupied portions of the strip of fabric projecting laterally from each side of the core. Adjacentto and arranged at the left of the rolls 9i and 95 is an'L-shaped member 97 secured to the upper face of the table 1 provided with an upwardly-extendingr and inclined arm 98 which engages the portion 99 of the fabric on the narrower side of the bead core (see Fig. 13) and its function is to commence the upward folding of the lateral-projecting portion 99. To the left of the member 9S is a foldingT device denominated generally by the reference numeral- 100 Fig. 16) and comprising an up; right frame 101 on which is a loop-'shaped havingy thumb nuts 103 so that the member 10Q may bc easily removed when desired. Secured to the frame 101 and projecting up-l warrlly in the path of the portion 99 of the strip S0 is a folding member 104 the function of which to. force the portion 99 of the strip 86 inwardly against the sharp or narrower portion of the bead core. The Vall of the member 102 which forms the left side of the cavity through which the bead-core passes in Fig. 16 isl'ongitudinally-inclincd so aS to be engaged by the portion 99 of the strip of fabric and. be
